Abstract:

This evaluation was made to ascertain the conformance of the Old Dominion Corporations Amplifier Demand Valve with previously set standards for scuba demand-type breathing equipment and to investigate its consistency of operation. The apparatus was evaluated objectively by breathing machine tests and depth swimming tests, with respiratory pressure instrumentation. It was evaluated subjectively by swimming pool runs. Breathing machine results are summarized as graphs of peak inspiratory pressure against cylinder pressure. Depth swimming test results are summarized as graphs of peak respiratory pressures, cylinder pressure, respiratory minute volume and respiratory rate, all against time. Subjective comments for swimming pool runs are given verbatim. The results are discussed and lead to specific conclusions about the apparatus.
